| Description | Johnsonella ignava is a gram-negative, curved rod-shaped bacterium that thrives in a temperature range of 25-45°C, categorizing it as a mesophile. This microbe is an obligate chemoheterotroph, meaning it cannot produce its own food and relies on organic compounds as its energy source. Johnsonella ignava produces energy through aerobic respiration, utilizing oxygen as a terminal electron acceptor. This microbe can be found in various body sites, including the respiratory, gastrointestinal, and genitourinary tracts of humans and animals, as well as in the environment, where it can survive in soil, water, and even on surfaces. Johnsonella ignava is an obligate aerobe, requiring oxygen to survive and grow. It is also a facultative anaerobe, able to tolerate low oxygen levels but thriving in the presence of oxygen. Johnsonella ignava is a slow-growing microbe, typically requiring several days to weeks to form visible colonies. Its growth is inhibited by high temperatures, desiccation, and the presence of certain antibiotics. Despite its relatively slow growth rate, Johnsonella ignava is capable of producing a range of enzymes, including cellulase, amylase, and protease, which enable it to break down complex organic matter. Notably, Johnsonella ignava has been associated with various human diseases, including respiratory tract infections, urinary tract infections, and skin lesions. Its ability to thrive in a wide range of environments and its potential to produce virulence factors have made it a subject of ongoing research in the field of microbiology. |
